recensies: I rarely use my 4 year old laptop on the battery, but when I did it only lasted about 25 minutes, so I decided to give this battery a chance for the sake of €22 or so.
The bottom line is that it works!
I can't remember off-hand exactly how much time I get on battery now, but it's around 2 hours at least.
One minor criticism, it was initially a slightly tricky to install the battery, it wasn't a 100% perfect fit. So the battery did fit in the battery compartment it took a little wiggling to get the battery clips to lock it in place. But it works and I can't complain about the price and would buy it again.
